Thank you so much! I applied your patch to 25.0.93 and tried it on OS X, both with and without NSTRACE_ENABLED. It does not count as a formal test, but I can confirm no crashes after minimizing/restoring about 20 times each. I did it because here Emacs crashed most of the time, but not always, and it seemed to depend on timings.
Best regards,
Ivan
